GeneTAC UC-4, AlphaArray.

Premium

Genomic Solutions of Ann Arbor, Mich., has released the GeneTAC UC-4, a new, high-resolution imager for detection and quantitation of microarrays printed on the entire surface of a slide-sized substrate.

The instrument can scan the entire upper surface of up to four 76mm x 25mm microarray substrates. The imager also comes with software designed to offer seamless workflow between scanning and analysis.

The instrument uses a removable, 4-slide universal carrier for rapid insertion and removal of samples. The carrier also reduces the need to handle slides, enabling rapid changeover between experiments.

Alpha Innotech of San Leandro, Calif., has unveiled the AlphaArray high throughput reader for microarrays. The AlphaArray can accommodate a variety of slide- or plate-based array formats and is available in two different models: the 7000, which offers automated multiple slide batch operation with eight excitation wavelengths; and the 6000, which offers single slide operation with two excitation wavelengths.

The AlphaArray also comes with a high performance Windows 2000/NT processor, reader unit, sample tray holder, and multiple copies of the advanced ArrayEase imaging software.
